Snapchat’s latest app redesign, aimed at broadening the appeal of the youth-oriented social network, sparked a backlash from many users complaining about the abrupt overhaul of their preferred service.

More than 578,000 users had signed an online petition by midday Monday calling on parent firm Snap to roll back the update, which was released last week.

“Many users have found that it has not made the app easier to use, but has, in fact, made many features more difficult,” the petition at change.org states.
